The traditional algorithm is inefficient in 3D faces point-to-point correspondence.To address this problem,an improved Active Shape Model(ASM)-based automatic 3D faces correspondence algorithm is proposed.The algorithm rapidly locates a 2D face.And accurately position the feature points in the texture maps of 3D models,which are generated by unwrapping 3D faces to 2D space.Feature location information is used to patch the unwrapping map.The resample algorithm based on the planer template is used to automatically achieve the pixel-wise correspondence between 3D faces.Experimental results show that the algorithm not only can improve the operation rate,but also the normalized results obtained remains 99% shape similarity with the original data.
